Abstract

A miniature temperature control structure for an electric heating piece contains a miniature temperature controller. The miniature temperature controller includes a circuit board on which a plurality of electronic parts are arranged, and the plurality of electronic parts at least has a microprocessor and an electrical contact portion disposed on the circuit board, the microprocessor has a thermostat program for setting a temperature value of each of a starting heating and a stopping heating based on requirement of an electric heating piece and for setting a heating time or a heating cycle time of the electric heating piece. Thereby, a size of the circuit board of the miniature temperature controller is decreased greatly to lower production cost of the electric heating piece and to carry the electric heating piece easily.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a miniature temperature control structure for an electric heating piece which miniaturizes a size of a circuit board of a miniature temperature controller to lower production cost of the electric heating piece and to carry the electric heating piece easily.BACKGROUND OF THE INVENTION[0002]With reference to FIG. 10, a conventional electric heating piece contains a control unit 11 for outputting electric current, a body 12, and an adjusting unit 13 for electrically connecting with the control unit 11, a first guiding wire 14 for electrically connecting with the control unit 11 and the adjusting unit 13, and a second guiding wire 15 for electrically connecting with the adjusting unit 13 and the body 12. The control unit 11 has a power supply 111 for accommodating a battery and supplying electric current from the control unit 11.[0003]However, the conventional electric heating piece still has the following defects:[0004]1. The...
